Modification in body weight associated with antiepileptic drugs Alteração de peso corpóreo associado às drogas antiepilépticas
Abstract
Antiepileptic drugs (AED) may cause body weight changes. OBJECTIVE: To evaluate the dietary habits and body weight associated with AED in epileptic patients. METHOD: Sixty-six patients were subjected to two interviews, and had their weight and body mass index calculated and compared at both times, interval between six to eight months. RESULTS: It was observed that 59.1% showed weight gain. The patients who had no weight gain had a greater proportion of individuals who engaged in some form of physical activity. However, of the 45 patients who maintained their initial dietary and medication pattern, 75.6% recorded a weight gain. Weight gain was seen in 66.7% of patients on carbamazepine (n=18), 60% on valproate (n=5), 50% on carbamazepine+clobazam treatment (n=14), and 58.3% of patients on other(s) polytherapy (n=12). CONCLUSION: The patient should be alerted to possible weight gain, and should be advised about dieting and participating in regular physical activity.Drogas antiepilépticas (DAE) podem causar alteração do peso corpóreo. OBJETIVO: Avaliar o hábito alimentar e do peso corpóreo associado às DAE em pacientes epilépticos. MÉTODO: Sessenta e seis pacientes foram submetidos a duas entrevistas, e tiveram peso e índice de massa corpórea (IMC) calculados e comparados nos dois momentos, com intervalo de 6 a 8 meses. RESULTADOS: Apresentaram aumento de peso 59,1% dos pacientes. Porém, os pacientes que não tiveram ganho de peso apresentaram maior proporção de indivíduos desenvolvendo alguma atividade física. Enquanto que dentre os 45 que mantiveram o padrão alimentar e medicação inicial 75,6% registraram ganho de peso. Observou-se ganho de peso em 66,7% dos pacientes com carbamazepina (n=18); 60% com valproato (n=5); 50% com carbamazepina e clobazam (n=14); 58,3% dos pacientes com politerapia (n=12). CONCLUSÃO: Deve-se alertar o paciente sobre o ganho de peso, orientar quanto à dieta alimentar e, principalmente, incentivar atividade física regular.
